    In the fllowing questions remember that a tomato is a fruit.

    I have presented a couple of ideas on how this might be done.
    
    I am presuming a random function that returns an integer between the 
    two arguments given.

    <outtext>
      Please select the fruit from the list below.
      
      This one attempts to be very simple I think to edit and recreate
      from the editor.

    <script>
      $numoftrueleafs=2;
      $numoffalseleafs=4;
      $numofpresentedleafs=4;
      $whichtrue=random(1,$numoftrueleafs);
      @whichfalse=pick(3,1,$numoffalseleafs); #pick(x,y,z), Picks x 
                                              #inetgers between y and z
    </script>

	maybe <block order="random"></block> is better? 
	The idea is that the following top level blocks get parsed in
	random order.

      <radio value=false condition="&ismemberoflist(1,@whichfalse)">
	Trucks
      </radio>

      Please select the fruit from the list below.
      
      This one attempts to be easier to type in by hand, but more
      troublesome to automate editing for. Also lets the parser been
      even less smart.

      @leafs=&map(randseed,$numpresentedleafs,(@trueleafs[$whichtrue],@whichfalse));
      @value=&map(randseed,$numpresentedleafs,('true','false','false','false'));

      Can tags inside a <script></script> be parsed? if so stick the
      radio button generation as a loop inside the script block.

	To have different options appear for different students.

	You could add conditions similar to the way the first radio
	button one works.
	
	Or you could do somthing along the lines of the second one and
	do all of the choosing in the script, setting a list of values
	and the associated text to that value.

	I could whip a couple examples of this up, but I think you
	could too.

	Tomatoes are <list value="1" possible="@options"></list>

      <outtext>
	<list value="1" possible="@options"></list> can be found
	growing on trees.
